AUTOMATIC GASOLENE VENDING APPARATUS.

Patented Sept. 14, 1915.

@Horns yf and also the plate to their normal positions. The slotted portion of the pull bar has a longitudinal movement in the grooves 53 formed opposite each other in the inner faces of said plates 48. The lever 49 is pivotally mounted upon a pin 54 carried by the bracket arm 55 which is fastened to the rods 7. The lower end of the lever is pivotally connected, through the medium of the pin 56, with the stem 6 carrying the valve regulatingthe exit opening in the tank.

Adtliatably mounted upon the stem 28 is a collar 60, and 61 designates a lever whichv is pivotally mounted upon a pin 68 carried by a dovnwardly curved finger 69 upon the arm 32 and one end or' the lever 61 is pivotally connected4 to the socket member 62 and its A -free end is disposed in the path of the collar upon the float stem. Said socket member 62 has interior threads therein for the reception of the upper end of the rod 62, and 64 is a jam nut mounted upon the threaded rod 63 and bearing against said socket member. A spring 65 is fastened at one end to said socket member and its other end to an adjustable screw eye 66 carried by thelloracket 67 upon the inner surface of the tan i The lower end of the rod 62 is pivotally connected to the long arm of the releasing latch lever 70 which is pivotally mounted upon a pin 71 carried by the hollow stem 12 and the short arm of the latch lever 70 is adapted to pass'througli an aperture 72, to engage the notch 8 in the hollow stem 6 when the float rises suiliciently to cause the collar on the stem thereof to tilt the lever 61, also the lever 70 connected thereto and which tilting movement of the latch lever, when it engages the notch in the stem, will cause the inlet valve to be retained open until the rod 63 is pushed down to throw the latch lever out of engagement with the notch in the hollow stem, after which the tension of the spring 16 will close the inlet valve.

The operation of the apparatus will be readily understood and is as follows: lVhen it is desired to dispense liquid from the tank, the coin is placed in the coin ,slot and falls down to a position behind thelever and adjacent to the inner curved edge of the plate 48X, the 'free end of which plate passes through the slot in the pull bar and is moved by the latter upon its outer throw. The apparatus is now in shape to allow the liquid to be dispensed when the pull bar is drawn out. The coin, which drops in the slot,

. lodges behind the lever and intermediate the sameand the free edge of the tilting plate 48x and, when the pull bar is drawn out, said plate will push the coin against the upper end of the lever and cause the same to 'tilt and, by reason of the lever 49 being pivotally connected to the valve stem, will impart an inner -longitudinal movement to the latter and open the valve 9 controlling the exit opening in the tank. By reason of the elongated slot in the pull bar, when the same isY released, the spring 49X will return the pull bar to its normal position independent of the movement of the lever, the latter swinging idly at its upper end in the slot of the pull bar when the valve stem returns to its normal position. As the stem moves to open the exit valve, the spring 14 will be put under tension and the pawl 21 will be thrown by the spring-pressed lever 2O into engagement with the notch 7 and hold the exit valve open. As the valve stem 6 is actuated by the lever 49, the short end of the releasing lever 70 will engage the notch 8, the lever 70 being held in its engagement with said notch 8 through the medium of the spring 65, the tension of which is regulated by the screw eye 66. When the float lowers riding upon the surface of the liquid and cornes in contact with the antifriction roller26, the lever 20 will tilt upon its pivot 19 and throw the pawl 21 out of engagement with the notch 7 in the valve stem and this will allow the spring 14 lto quickly cause the valve controlling the exit opening to seat and shut oil further dispensing of the liquid.

Simultaneously with the closing movement of the valve regulating the exit opening, the hollow stem 12.l which is connected to the valv- 13 regulating the inlet opening, will be caused to move with the stem 6 by reason of the short end of the lever 7 0 being in engagement with the notch 8 and thereby quickly opening the inlet valve and which movement of the hollow stem will put the spring 16 under tension. The exit valve being closed and the inlet valve being open, the tank will be replenished with liquid to its measured capacity and, when the collar 60 comes in contact with the lever 61, the latter will tilt and, through its connection with the lever 70, will cause the latter to tilt and release its opposite end from. the notch 8, thus allowing the spring 16 to return the hollow stem to its normal position and cause the inlet valve to seat.

It will be noted that, as the float lowers, which will take place during the dispensing of the liquid, the slide 41 will automatically close the coin slot to prevent the insertion of the coin until the supply of liquid in the tank is replenished. the slide rising with the float by reason of the stem of the latter coming in contact with the lever carrying the slide.

By the provision of an apparatus embodying the features of our invention, it will be noted that a simple and eilicient gasolene vending apparatus is provided in which the mechanism is automatic in its action, positively shutting 01T the supply after the measured quantity has entered the receptacle.
